qimager.setoptions

Set some general options for subsequent processing

Synopsis setoptions(ftmachine, cache, tile, gridfunction, padding)

Description Various less-often-used options for processing can be set.

ftmachine

The options for ftmachine are:

wproject: W projection algorithm.
mosaic: Mosaic gridding.

cache

The size of the cache used (in complex pixels) during the gridding process. The default is to use half the physical memory of the machine as specified by the aipsrc variable system.resources.memory.

tile

The side of the tile (in complex pixels) during the gridding process. are supported.

Arguments

`ftmachine`	Fourier transform machine
	`Allowed:`	`String:'ft'\|'sd'\|'both' \| 'wfmemoryft'`
	`Default:`	`'ft'`
`cache`	Size of gridding cache in complex pixels
	`Allowed:`	`Int`
	`Default:`	`4194304`
`tile`	Size of a gridding tile in pixels (in 1 dimension)
	`Allowed:`	`Int`
	`Default:`	`16`
`gridfunction`	Gridding function
	`Allowed:`	`String: 'SF'\|'BOX'`
	`Default:`	`'SF'`
`padding`	Padding factor in image plane (>=1.0)
	`Allowed:`	`Float`
	`Default:`	`1.0`

Returns Bool

Example

- imgr.setoptions(cache=10000000, tile=32, gridfunction='BOX',
  dm.location('vla'))
